Document Summary

It only lays on top of the ribs: articulates indirectly with the axial skeleton through the clavicle, sternum: is part of the axial skeleton. Sternoclavicular joint: clavicle articulates with the manubrium, the clavicle has to be strongly connected to the. Small disk lays inside this joint manubrium: this is done by these 3 ligaments. Sternoclavicular ligament: links the sternum with the clavicle, surrounds the sternoclavicular joint. Interclavicular ligament: connects the two clavicles together, costal-clavicular ligament, connects the 1st ribs to the clavicle. Lies horizontally across the anterior part of the thorax superior to the first rib. Defining feature - smooth surface: the top of the bone is very smooth, underside is very rough and rigid, this is where many ligaments attach. Medial vs. lateral ends of the bone: medial or sternal end, square end to the bone, forms the sternoclavicular joint. Lateral end: very flat, looks like a (cid:271)ea(cid:448)er"s tail, articulates with the scapula.
